The Infra­structure & Support Functions division

The Infrastructure & Support Functions division is responsible for our network and IT infrastructure, which we also provide to third parties over Wholesale. Broadband requirements double in the fixed network sector every 16 months and in the mobile sector every year. This is why we invest around CHF 1.7 million annually in expanding our infrastructure. We are by far the largest provider of fixed and mobile networks in Switzerland.

The Swisscom network

One of the best in the world

Network infrastructure forms the basis for digitisation and is a fundamental requirement for technological development. Networks provide us with both a local and global connection, and enable us all to utilise the advantages of an information society. The Swisscom network is one of the best in the world and we will do our utmost to ensure that this does not change in the future.
